As to the formidable diseases which are common to both, their occurrence in either is characterised by the same appalling manifestations: dysentery fastens, with all its fearful concomitants, on the unwary and incautious; and cholera, with its dark horrors, sweeps mysteriously across neglected districts, exacting its hecatombs.

But the visitation and ravages of both are somewhat under control, and the experience bequeathed by each gloomy visitation has added to the facilities for checking its recurrence.[1] [Footnote 1: "It is worthy of remark, that although all the troops in Ceylon have occasionally, but at rare intervals; suffered severely from cholera, the disease has in very few instances attacked the officers; or indeed Europeans in the same grade of life.

This is one important difference to be borne in mind when estimating the comparative risk of life in India and Ceylon.

It must be due to the difference in comforts and quarters, or more particularly to the exemption from night duty, by far the most trying of the soldiers' hardships.

The small mortality amongst the officers of European regiments in Ceylon is very remarkable."-- _Note_ by Dr.CAMERON, Army Med.
